Frisk walked down the hall in her bra and underwear (trying to not wake tori or papyrus up)and opened Sanses door "hel-lo frisk" sans said smiling putting out his cigarette.she giggled and climbed on his lap he fell back he grabbed frisks tight ass he smacked it she giggled he rolled so he was on top he took off her pink lace panties and shoved his fingers in her still super tight pussy his fingers fit perfectly in her cunt he pulled them out, licked them and stuck his long tongue in her pussy she moaned "shiit"
She grabbed him,ripped his pants off,and sucked his long hard cock "fuuuck frisk if you keep this up I'm gonna cum before I'm inside you" he grabbed her and pulled her towards him he shoved his giant cock in her cunt "fuuuuck sans it's so biiiig" "yes yes yes yes YES YEEES" he thrusted harder and faster "YEEEEEEESS YOUR CUNT IS AMAZING FUCK" he screamed thrusting his erect cock farther into frisks fragile small body 5 mins later they came again together.

"Well how do I look?"frisk said in her present it was dark red lace lingerie
"Do a turn"sans said moving his finger in a circle.frisk twirled smiling."come here let's try 'em out"sans said sitting up frisk laughed as she jumped on his lap her blonde hair was down to the backs of her knees it was everywhere.the top of the lingerie was her size exactly. perfectly tight in the right spots.the bottom was lace panties that connected to thigh high stockings.sans grabbed her waist kissing her, their tongues intertwining with saliva and passion.he licked her neck up to her ear and whispered " I bought an extra one so I can be as rough as I want with you"he laughed she moved closer and whispered "bring it" he grabbed her hair and yanked her head to one side as he licked her neck and bit it with his sharp teeth she let out a small moan.she took off his coat,as she kissed him she rubbed his already hard cock through his shorts he flinched as she took it out of his pants she rubbed her tongue on it then she deepthroated it sans moaned as he pulled her hair.he grabbed her wrists as he pinned her hard against the bed he had two magic hands keep her arms and legs pinned to the bed then he moved his hands down her body and stopped at her pelvis,he rubbed her wet pussy through the lingerie she let out a moan he ripped the panties so he could stick his tongue in her pussy he ripped the top of her lingerie with more magic hands she moaned louder as Sanses hands grabbed her huge breasts then he thrusted his huge erect cock in her small pussy it felt like it was gonna come out her throat she moaned really loud,the hands moved to her breasts and were caressing them roughly,they pinched her erect nipples. sans lifted her legs almost behind her head he smiled that she could bend so easily "GOD YOUR PUSSY IS SO TIGHT FRISK!!!" Sans said pinning her wrists down "FUCK SANS YES HARDER PLEASE!!!!" Frisk yelled moaning loudly.sans moaned loudly.just then the door flew open it was papyrus "sans pick up your damn sock-"papyrus stared at them in disbelief frisk and sans looked at him shocked "we-I-uh-well oh god"sans said looking at frisk she was speechless "DO.NOT.TELL.TORI" frisk yelled just then papyrus ran down stairs "TORI" he said screaming down the hall "NO" sans screamed putting his shorts on "damn it" he tripped.he threw his shirt on and slid downstairs frisk quickly took off the remaining lingerie,ran into her room and put on her cupcake pyjamas, tied her hair in a messy bun,and slid down the railing. "PAPYRUS PLEAAAASE! don't do this"sans begged just then frisk slid down the hall in her pjs and socks "papyrus please no-woah-oh"frisk smacked into a wall "I'm ok" sans used his magic to bring frisk over papyrus banged on Tori's door "don't make me papyrus" sans said with his eye glowing."I told you not to fall in love with a human,I warned you".papyrus said glaring down at sans.(by the way Toriel in my A.U.
